The biggest one I've ever seen was on my college roommate. He was a curly haired blonde with the thickest 10" of cut meat I have ever seen. I had never done anything previousl;y, but he always took opportunities for me to "catch" a look at his huge schlong. He was about 6" soft, very thick. He was a full 10" maybe 11" when really horny. One night after partying I found him standing over my bed with a hard-on, softly rubbing my forearm with it. I pretended to sleep, but couldn't stand the excitement any longer and finally starting stroking and then sucking this beautiful cock. It was very straight, with plum-sized balls hanging down. We got into a routine of doing this and eventually I let him fuck me with that thing. It took a long time for me to be comfortable withit, but soon became a whore for his huge cock. We fucked several times a week for 2 1/2 years. He liked taking my 8" as well. I felt tiny compared to him. We eventually graduated and I lost touch, but still (30 years later) still jack off thinking about his gorgeous cock. I haven't seen a better looking one posted anywhere. (Bigger, but not as perfect in shape, thickness, etc.) He was the first person I ever swallowed cum from, also. He was the total package.
